Glass hair is hair so smooth and shiny that it looks like a sheet of glass, with all of its movement still intact. It is the finish our clients ask about most after seeing SB Custom Smooth results, so here is what it is, how the transformation looks from start to finish, and what to know before you book.

What is glass hair?
Glass hair is a look, not a product. It is hair that looks incredibly smooth, reflective and polished, with beautiful movement. When the surface of the hair is smooth, light reflects evenly along each strand, and that is what gives it the glossy, mirror-like finish people love.
At Salon Bravissimo we get there with SB Custom Smooth, a professional smoothing treatment designed to turn frizzy, unruly or hard-to-manage hair into hair that feels smoother, softer, shinier and easier to style.
What does the transformation look like?
These three frames come from a single SB Custom Smooth treatment: the natural texture before, the finished result, and the hair after its first wash. The first wash matters because it shows what clients will actually live with at home.



Our stylists also share short videos of each stage, plus more results, on the SB Custom Smooth page and on Instagram.
How is SB Custom Smooth different from other smoothing treatments?
It is not a one-size-fits-all service. A trained stylist customizes the treatment to your hair texture, your hair condition and the result you want. That is why two clients can both have SB Custom Smooth and walk out with different looks.
Clients tell us they love that it:
- Dramatically reduces frizz and unwanted volume
- Creates shine and a smooth, polished finish
- Makes blow-drying and daily styling easier
- Helps improve manageability in humid weather
- Can keep your natural movement or create a straighter, sleeker finish
Will my hair be pin straight?
Only if you want it to be. Not everyone wants pin-straight hair. Some clients want to keep their natural body and movement while controlling frizz, and others want a much smoother, straighter result. Your stylist plans the treatment around the result you choose, which is why every treatment starts with a conversation.
Is SB Custom Smooth right for me?
It may be a great choice if you struggle with:
- Frizz and puffiness
- Humidity
- Unwanted volume
- Difficult blow-drying
- Coarse texture
- Long styling time
- Lack of shine
Not sure which smoothing service fits? Our stylists can explain the difference between SB Custom Smooth, Keratin Complex smoothing and Yuko Japanese hair straightening, and recommend the one that suits your hair and your goals.
What happens at the consultation?
Every SB Custom Smooth treatment begins with a professional consultation. Your stylist looks at your hair history, texture, condition and goals before recommending the treatment that is right for you. This is also the time to ask about the finish you want, how it will behave when you wash and style it yourself, and how to care for it at home.
How much does SB Custom Smooth cost?
SB Custom Smooth starts at $350. Final pricing can vary with hair length, density, condition and the amount of product and time your hair needs. Your stylist confirms your price, and you can ask for a quote before your service starts.
Where can I get SB Custom Smooth?
It is available at all three Salon Bravissimo locations: Fair Oaks Blvd and Howe Ave in Sacramento, and Historic Folsom. Book online, or call (916) 972-7273 to schedule your consultation.
